摘要

三维医学影像的出现是诊断各种疾病的转折点,因为相邻切片的体素信息有助于放射科医生更好地理解复杂的解剖关系。然而,不同专业水平的放射科医生对医学影像的解读可能各不相同,而且耗费时间。在过去几十年中,基于人工智能的计算机辅助系统提供了快速、更可靠的诊断见解,在各种临床用途中具有巨大潜力。本文提出了一种重要的基于深度学习的三维医学图像诊断方法。该方法对 MedMNIST3D 进行了分类,MedMNIST3D 由六种三维生物医学数据集组成,分别来自 CT、MRA 和电子显微镜模式。所提出的方法将从三个独立网络、一个 3D CNN 和两个时间分布 ResNet BLSTM 结构中提取的 3D 图像特征合并在一起。通过最小冗余最大相关性(mRMR)特征选择法选出最终的判别特征。然后通过神经网络模型对这些特征进行分类。实验遵循 MedMNIST3D 数据集的官方拆分规则和评估指标。结果表明,所提出的方法在准确率和AUC方面优于同类研究。

An Efficient and Robust 3D Medical Image Classification Approach Based on 3D CNN, Time-Distributed 2D CNN-BLSTM Models, and mRMR Feature Selection

The advent of 3D medical imaging has been a turning point in the diagnosis of various diseases, as voxel information from adjacent slices helps radiologists better understand complex anatomical relationships. However, the interpretation of medical images by radiologists with different levels of expertise can vary and is also time-consuming. In the last decades, artificial intelligence-based computer-aided systems have provided fast and more reliable diagnostic insights with great potential for various clinical purposes. This paper proposes a significant deep learning based 3D medical image diagnosis method. The method classifies MedMNIST3D, which consists of six 3D biomedical datasets obtained from CT, MRA, and electron microscopy modalities. The proposed method concatenates 3D image features extracted from three independent networks, a 3D CNN, and two time-distributed ResNet BLSTM structures. The ultimate discriminative features are selected via the minimum redundancy maximum relevance (mRMR) feature selection method. Those features are then classified by a neural network model. Experiments adhere to the rules of the official splits and evaluation metrics of the MedMNIST3D datasets. The results reveal that the proposed approach outperforms similar studies in terms of accuracy and AUC.
